Afer taping her appearance on the Tonight Show with Jay Leno Friday, Christina Aguilera and boyfriend Matthew Rutler headed to Spago in Beverly Hills to celebrate the release of the singer's latest video, "Your Body."

Christina wore the same dress she wore on the Tonight Show, but left the restaurant looking decidedly less polished. Dlisted reports that dishwashers at Spago had to stay two hours past their shifts to scrub stains off the red wine glasses. We're not sure about that, but it does look like Christina may have had more than one or two drinks.
